Gestational diabetes is a form of diabetes that occurs in women during pregnancy.
About 12–14% of pregnant women will develop gestational diabetes, usually around the 24th to 28th week of pregnancy. This is diagnosed with an Oral glucose tolerance test.
Most women will no longer have diabetes after the baby is born. However, some women will continue to have high blood glucose levels after delivery.

Managing gestational diabetes can help keep blood glucose levels in the target range for a healthy pregnancy.
